These autos are 6 weeks, just been feeding it water as I’m using FFOF. Ppms are still over 1000. I read that autos need way lower ppms compared to photos. Leaves are currently drooping, each plant takes about 3/4-1g of water. Is this a sign of overwatering, under watering, and/or lack of nutes. pH is in the range of 6.2-6.5, temps between 71-78, humidity between 48-55%

Drooping around watering time is normal. It should persist for several hours (up to 1/2 day at most.)

During veg under 2000ppm runoff
During flower I like to hang around 12-1600ppm runoff. Always start with half dose and work your way up. No one plant, auto or photo is gonna be the same or react the same as another.
As for feed tds, no more then 1k is really worth pouring in, IMO. Too hot.
Plant looks happy.
It can be, depends on how dry your soil is on water/feed days, also could be a sign of less then desireable environment. How often are you watering since your environment seems on point?

I water every 2-3 days, usually I stick my finger in the soil to the first my knuckle to see if it’s dry as well as the weight of the pot. I also have a meter to check the dryness of the soil.

What size pot is that? Just curious mostly. Best to ya on the rest of your grow. Got her looking good though.

They are all in three gallon pots. Thanks, this is the first time I’m doing autoflowers after I harvested some photos just to compare. This strain is Bruce Banner

Want to try that strain too at some point and strawberry cough. Think these are the two I’m gonna try next. She should perk up soon. Mine went through the same mini phase about that age too just not long ago but are thriving now. Keep up the good work.

Thanks I appreciate the feedback. I always wanted to try the strain as well because I’m a big sativa fan. I just bought seeds of Ghost train Alaskan Thunderfuck, Chernobyl and Blue dream. One’s on my list that I always wanted to try

follow a drench to drought routine Growmie. Soak the pot to liberal run off then let it go through the dry cycle. Roots need the dry cycle for oxygen. Over watering is frequency related not the amount given at one time

Can anyone advise me if the yellow/lime green leaves are a sign of overwatering or lack for nutes?
They are on week 8, I just flushed with Sledgehammer, yesterday. The top right plant seems ok with dark green leaves, the top left shows more yellow leaves and the bottom right seems ok but leaves are like green

What brand nutes are you using? Not familiar with sledgehammer but I use green planet.

Sledgehammer is from Fox Farms, so using their nutes.

Huh, used their system a while ago but just basics.
Ok, here is the graph I like for deficiencies and toxicity
I hope this helps. They look like they could use a little calmag possibly…nitrogen too…other folks will be able to give better instruction than I can.

Yeah I have that same pic, Im leaning towards nitrogen deficiency. What’s weird to me is that all 3 are using the same medium and same watering schedule, and one out of three have the normal looking dark green leaves(top right plant). Thanks for the feedback, I’ll feed it more nitrogen once it’s time to water again
Each plant has its own needs. Some just crave nitrogen, others need other stuff.
